AUTOMATIC VARIABLE SPEED PNEUMATIC HACKSAW MACHINE
ABSTRACT:
The hacksaw is a metal slicing machine apparatus intended to cut metal by applying pneumatic weight. The machine is solely planned for large-scale manufacturing and they speak to secure and more productive approach to cut a metal.
Hacksaws are utilized to cut thin and delicate metals. The activity of the unit is streamlined to a couple of straightforward tasks including a chamber square and cylinder game plan. There are various kinds of cutting machines in Engineering field, which are utilized to satisfy the necessities. We are intrigued to present the pneumatic framework in Hacksaw machine. The primary capacity of Pneumatic hacksaw is to cut thin and delicate metals by pneumatic power.
PRESENTATION:
Requirement FOR AUTOMATION
These days all the assembling procedure is being automized with a specific end goal to convey the items at a quicker rate. The assembling task is being automized for the accompanying reasons.
To accomplish large scale manufacturing
To diminish labor
To increment the productivity of the plant
To diminish the work stack
To diminish the generation cost
To diminish the generation time
To diminish the material taking care of
To diminish the exhaustion of specialists
To accomplish great item quality
Less Maintenance
PRINCIPALS OF WORKING:
The packed air from the compressor achieves the solenoid valve. The solenoid valve alters the course of the stream as per the signs from the planning gadget.
The compacted air go through the solenoid valve and it is conceded into the front end of the chamber square. The air pushes the cylinder for the cutting stroke. Toward the finish of the cutting stroke air from the solenoid valve achieves the backside of the barrel square. The weight continues as before however the zone is less because of the nearness of cylinder pole. This applies more noteworthy weight on the cylinder, pushing it at a speedier rate subsequently empowering quicker return stroke.
The weight joined toward the finish of the hacksaw outline gives steady loads which bring down the hacksaw to empower persistent cutting of the work.
The stroke length of the cylinder can be changed by making an appropriate alteration in the clock.
ADVANTAGES:
There is no need of giving food amid each slice because of the nearness of weight.
The cutting pace can be shifted by our requirements by altering the clock.
It is versatile
It does not have any Prime mover, similar to electric engine identified with the unit.
As the air is uninhibitedly accessible, we can use the air to cut the metal and subsequently it is sparing.
Simple in development than a mechanical hacksaw
It is a conservative one
Less Maintenance
DISADVANTAGES:
Only littler size and delicate metal can be cut
It is costlier than the mechanical hacksaw due to the compressor unit.
Less effectiveness when packed to the mechanical gadget.
Leakage of air influences the working of the unit.
